l To crZZ whom t may concern Be itknown that l, JOHN E. GABLE, a

resident of Evanston, in the county ofI Cook..

and State oflllllinois, have invented certain new and usefulimprovements in Well- Pil-mp5. of which the following is a full, clear,and exact description.

rfhe invention relates to' pumping-appa ratus for wells.

ln well-pumping apparatus heretofore devised in which a rotary pump wasemployed for lifting the liquid it has been necessary to provide a pipefor conducting the Huid y from the pump at or near the bottom of t-hewell tothe surface and in addition thereto another longitudinallyextendm element,

such as a shaft for operating or e ect-ing ro-" tation of one of thepump elements necessary to raise the water to the surface and throughsaid pipe. Une of the main objects of the present invention is toprovide an improved apparatus in which the pipe through which the wateris lifted serves also as means for transmitting power or revolution to'one of the pumpelements necessary to cause the water to be liftedthrough the pipe. Resultantly, when a pipe serves the double purpose ofa Huidconductor and a drive-shaft, the necessity of employing a shaftextending from the top to the bottom of the well is avoided. Thisfeature of advantagel is particularly important in deep wells.Furthermore, all 'the attendant disadvanta es of employing a long shaftor line of sha ting, likely to become out of alinement will be entirelyavoided.

Thel invention further esigns to provide improved mechanism which willbe automatically secured in the well-pipe when lowered to then bottom'thereof to hold one of the pump-elements to eect proper coperation ofthe several elements of the pump.

The invention also designsto provide improved pumping-apparatus forWells', which is simple in construction and eiiicient in operation.

lIn the drawings: Figure l is a' section of a Well and apparatusembodying theinvention. Fig. 2 is a section on an enlarged scale takenon line 2-2 of Fig. 1. Fig. 3 is a section on line 3-3' of Fig. 2. Fig.4 is a section through the pump-anchor. Fig. 5 is' a section on line 5-5of Fig. 4.

A. denotes a sunken well-pipe extending from the bottom lof the well tothe usual platform b on the surface of the ground. A pipe c extendsvertically through the well-pipe and is journaled near its upperv end 1na suitable bearing d on a suitable support e. A head j" is connected tothe open upper end of the Well-pipe and support d 1s mounted, forconvenience, von sald head. A chamber f is formedin the head f and oneor more pipes f2 are connected to said chamber to carry of the gasesfrom the well-pipe when the improved apparatus is employed for pumpingoil-wells or those containing gases. Pipe c extends through a suitablepacking-.box f3 in the head f to prevent leakagel of gases around thepipe. A pulley g is secured to the upper end of pipe c, serving as ameans for driving or rotating said pipe.

The `liquid is raised fama@ wen by' a rotary-pump if: which forces itthrough the pipe c. A pipe-terminal Zz having out-let openings h thereinis secured to the upper end of the outlet pipe o and on the upper end ofsaid4 head, is a suitable bearing f1.2 for a casing z', into which the.liquid is discharged through the openings h in the pipehead ZL and alpipe j may be. employed for conducting the fluid to any point desired.

Rotary pump lc serves as the means for lifting the liquid fromthe"bottom of thev well, through the pipe c and into the casing z'.Thisxrotary pump comprises essentially other to force fluid through thepipe c. In

the embodiment offthe invention illustrated, the pump Casing Ic issecured to rotate with the pipe c and a part of the piston is heldagainst rotation with the casing to effect the relative movement of thepump elements to force the4 Huid upwardly through the pipe c.

An anchoring-device Z adapted to be automatically secured to the welli eA when the pump is lowered, is providd) for securing one of thepump-elements against rotation with the pump-casing to render the pumpoperative to lift the liquid. This anchoring-device Z comprises a pairof Wed eblocks Z', Z2, slidably connected together y pins Z3, and slotsZ4 formed in the wedgeblocks respectively so that when theanchoring-device is lowered in the Well-pipe and the wedge-block Z2encounters an obstruction, such as the bottom of the well, it will bearrested and the other wedge-block Z may be forced downwardly to causethe anchoringdevice to' become` locked to the well-pipe,

thus securing it against rotationl therein.

The connection between the upper wedgeblockZ and the pump-pistonconsists of a rod m having itslower end slotted'and4 an elongated eye Z8or staple n on the wedgeblock ZV `which extends through the slot in thelower end of the rod vm. This constitutes a lost-motion connection topermit relative vertical movement of. the pump-rod lwith respect to vtheanchoring-device but raise the wedge-block Z until the-anchoring devicehas been unlocked or released from the well-pipe. Therefore thisanchoringdevice' is automatically rendered operative and inoperativewhen the pump is lowered or raised respectively. l'

The pump employed is preferably one which forces the liquid upwardly andpositively; The lower end of the pump-casing is connected to a pipe 7c3having perforations y 709 therein, through which the liquidwill pass tothe inlet-chamber 21 ofthe casing at,

one side'of the piston. The piston .comprises a pair of toothed members71:5 and k6, geared together by pinions le" and ks. The

piston-members have longitudinally interlitting ribs or faces andgrooves so that when they are rotated relatively, fluid. will not passbetween the Vpiston-members. The pump-casing is provided with-asegmental inner periphery 20 at each side of one of the well-pipe, apipe in the well-pipe, means for piston-members so that during relativerotation of the casing with respect to the piston-members the fluid inthe spaces between the outer ribs of the piston-members will be confinedbetween the piston-members and the walls 20 andforced from theinlet-chamber 21'to the outlet-chamber 22 atl the opposite sides o f thepiston-members. Each plstonmember is provided with a stud or shaft 23,journaled in `horizontal walls 24 and 25 at the top and bottom of saidmembers respectively.v An internally toothed gear 30 is .secured totheupper end of anchor-rod m which meshes with a pinion 31 on one of thepiston-studs. In operation, when the-pumpcasing is rotated, one of thepiston-members being held against rotation with the pump` casing by theanchor-rod m and gears 30 and 31, relative rotation of thepiston-members with respect to the piston-casing will result to causethese members to force the liquid from the inlet-chamber to theAoutletchamber of the casing. Resultantly, the

forced into the ground, the pipe c with thev pump and anchoring-deviceconnected-to its lower end, is lowered into the well-pipe. When thelower wedge-block Z2 encounters the bottom of the well it will bearrested chor-rod m will then force the upper wedgeblock Z downwardlyuntil the anchoringdevice has been locked to the well-pipe. Theapparatus at the upper end of the well-pipe being then in place, pulleyg will be driven to rotate the pipe c which will operate the rotary-pumpto raise and force the liquid through the pipe c into the casing z'.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent, is

1'. In a well-pump, the combination of a well-pipe, a plpe extendingldownwardly into the well-pipe, means for rotating said inner pipe, arotary pump in the well-pipe and comprising a piston and aycasing, saidcasing being connected to the lower end of said pipe and driventhereby,`the piston comprising a plurality of members pivoted in thecasing, and a vertically adjustable anchoring device in the well-pipeand connected to one of the piston members 'for holding it to causerelative rotation of the pump and piston.
